STEWART ROY ILLINGWORTH, OF BRYNFEDVIEN, BADYR, -WALES,'ASSIGNOR.TO THEILLINGWORTH GARBONIZATION' COMPANY, LIMITED, 'MANCHESTER,-ENGLAND.

AGITATING APPARATUS.

Application filed July 16, 1928,'Seria1 No. 293,105, andin GreatzBritainJune 15, 1927.

This invention relates to improvements in or modifications of theinvention described in my former specification No.'1,593,698 whichrelates to the cooling of coke andapparatus therefor.

' The present invention relates more particle larly to the. constructionof the cooling wagon as illustrated in Figures 58 ofmy formerspecification and which comprises a cylindrical chamber mounted torotate on a carriage which can be moved to receive the discharge fromany of the retorts or beneath the measuring hopper and the dischargepipe from the cistern.

Great difiiculty, however, is experienced in opening and closing the.door or doors of the cooling chamber, owing to the heat given outby thehot coke from the retorts, since it has to be operated by hand and it isthe object of this invention to overcome this defect.

According to this invention, means is provided preferably mounted'on thecarriage of the cooling wagon and adapted to be moved into or out ofengagementwith the door or doors of the cooling cylinder or chamber, sothat when in engagement therewith the door or doors, may be operated toopen or close by the rotation in one or the other direc tion of thecooling chamber or cylinder.

In one construction these doors may be of the sliding type, arms or clawmembers being provided pivotally mounted on the carriage so as to becapable of movement into the path of the doors to engage therewith, thepivot point of said membersbeing such that when moved into engagementwith the cylin der, they rest thereupon under the action of gravity. Theclaw members maybe carried on one shaft mounted in bearings on the car'riage parallel to the axis of rotation of the cylinder and providedwith a lever for moving the claw members into and out of the path of thedoors, the claw members in the 7 normal or disengaged position restingagainst a cross bar on the carriage.

The claw members'may consist ofeurved arms, havinga curvaturesubstantially equal to that ofthe cylinder, their outer ends beingprovided'with'T shapedslots adapted to engage and pass over a rod or thelike on the doors, and having an outward or reverse curve from the slotsto the tips. Preferably means provided for locking the doors in thesition.

i bees-i. on

" sliding doors, following which, further rotation in the desireddirection, moves the-rods or the like into'one of the sides ofthe Tshaped slot," when on further rotationof theycylinder the doors may beopened or closed as desired.

Thedisch'arge means for the steam orother gases from the cooling chamberor cylinder comprises a series of holes which are formed 1n the endthereof, an'da covering plate in which is a slotadapted to registerwithone or other of the holes to allow the passage of steam orother gases.

Preferably the slot is of suclra size that only the equivalent of onehole may register therewith, that is the circumferential length oftheslot is equal to the distance between the centres of two holes. a

The plate which is preferably of;annular form may be positioned by meansofthree or n ore rollers'mounted on the end of'the cylinder and engagingthe periphery of the plate so that the eylinderis free to rotate withrespect thereto, fingers on the cylinder-engaging the face of the plateand causing it to bear against the end of the cylinder.

Preferably the plate is fixed or its movement restricted by means suchas a stop or stops such that the slot always remains in its A'flange ordeflection plate may be provided around the lower portion of the edge ofthe slot.

The construction relating to the means for permittingthe escape of steamand gases from the cooling chamber is claimed in a divisionalapplication, Serial No. 335,314, filed January 26, 1929.

IA coolingwagon constructed in accordance with the,presentinvention thusforms a selfcontained unit and maybe provided with a Chamber or cylinderB the carriage thereof mounted on wheels C which run on a track D. E arethe driving gears. F are doors on the periphery of the cylinder A. G arevent holes for the escape of steam from the cylinder.

The cylinder A is rotatably supported on rollers 1 mounted in hearingson plates 2 carried by the carriage B. l he rollers 1 are flanged andengage endless rails 3 at each end of the cylinder A, which is guidedaxially by side frames indicated generally at 5. Additional rollers 6are provided for preventing any rolling movement-of the cy inder. 7 is aplatform carrying the driving mechanism for rotating the cylinder andoperating the earriage and provided with two sets of uprights S and 9. v

The outermost uprights 8 carry hand rails 1 and the innermost uprights 9are formedwith bearings 10 for a shaft 11 on which curved arms formingthe claw members 12 arosecured for operating the doors F.

lhe arms 12 are slotted at their ends as shown at 13 and are adaptedwhen moved into engagement with the cylinder to engage pins or bars 1 1carried in plates on the doors F, which are slidably opened (see Fig. Itwill be noted that the surfaces of the arm 12 extending away from theopen side of the slot '13 are formed so as to present cam surfacesadapted to be engaged by the pin 14 upon rotation of the chamber tothereby raise the arm and then to automatically lower it to bring thepin 14 and the slot 13 into interlocking engagement.

In the modification shown in Figure 4 the arms 12 have pins 13 adaptedto engage slots or recesses l t in plates 15. The arms 12 are as shownmounted in pairs jointed to one another by cross pieces 16 and rotatableabout the shaft 11 which may be by hand by a lever X mounted on theshaft. lhe arms 12 in the unengaged position rest against a bar 17secured to the uprights 9 which are extended upwardly for this purpose.It is to be observed that the projecting portions of the plate 15" arespaced to form a resultant groove 14;, and that these projectingportions are formed so as to present cam surfaces adapted to engage thepin 13 carried by the lever upon rotation of the chamber and to raisethe lever and to allow the lever to be automatically lowered to bringthe pin and the slot into interlocking engagement.

The doors F may be locked (see Fig. 1) by means of bolt pieces 18mounted to slide in holes in the plates 15 and which, when in the lockedposition as shown engage slots 19 formed on the periphery of thecylinder. The bolts 18 are pivotally connected at their inner ends tooperating handles 20, pivotally mounted on the doors F at 21 and movableto and fro to lock and unlock in guides 22.

In operation, the doors are first unlocked by moving the handles in thedirection of the arrows. The arms 12 are now moved to engagethe cylinderA which is then rotated and the doors opened by engagement of the slots13 with the bars 14:. I

Referring more particularly to Figure 2 the cylinder A is provided witha ring 23 adapted to close all except one of the steam vents G. The ringis freely mounted at its rim on rollers 2-1- mounted in bearings 25having fingers 26 for holding the ring against the end of the cylinder.The ring is provided with a slot 27 of such a size that at any time avent G or portions of two vents, substantially equivalent to a wholevent remain or remains uncovered. The vent G is shown uncovered. Theslot 27 is provided with a de- Elector plate 28. 29 are stops to preventrotation of the ring 23.

From the foregoing it will be apparent that y in using a cooling chamberconstructed in. ac-

cordanee with my invention the opening of the door is necessary in orderto admit a charge of coke may be accomplished by a slight rotation ofthe chamber, and the closing thereof subsequently accomplished by anequally slight rotation of the chamber in the opposite direction.Because of this construction, the opening maybe removed from registrywith the door at a point near the top of the drum and then returned toregistry with the door without moving the opening to a position be lowthe axis of the chamber. It will thus be seen that, if the chambercontains a charge of coke or a portion of a charge and it is desired toadd more coke without discharging that already in the chamber, the doormay be opened, the additional coke introduced, and the door then closedwithout its being necessary to bring the door into a dischargingposition.

It should be understood that apparatus constructed in accordance withthe present invention is suitable for use with other materials and theinvention is not limited to the treatment of coal and coke.

lVhat I claim is 1. In an agitating apparatus, the combination with asupport; of an agitating cooling chamber mounted thereon for rotativemovements in opposite directions and provided with an opening to admit acharge of mate rial, a sliding door carried by the chamber and adaptedto close said opening; and looking means adapted to be moved intopositive interlocking engagement with the door to hold it on rotation ofthe chamber in both of its opposite rotative movements to thus move saidopening relative to the door.

2. In an agitating apparatus, the combination nu'th a support; of anagitating chamber mounted thereon for rotative movements in oppositedirectionsand provided with an opening to admit a charge of material; asliding door carried, by the chamber and adapted to close said opening;and a pivoted lever movable into interlocking engagement withcooperating means onthe door to hold said door stationary on rotation ofthe door in both of its opposite rotative movements to thus move saidopening relative to the door;

3. In an agitating apparatus, the combination with a support; of anagitating chamber mounted thereon for rotative movements in opposite,directions and provided With an opening to admit a charge of material; asliding door carried by the chamber and adapted to close said opening;and locking means movable into engagement with the door, and havinginterlocking pin and slot connection therewith when in engaged positionto hold said door stationary on rotation of the door in both of itsopposite rotative movements to thus move said opening rela tive to thedoor.

In testimony that I claim the foregoing as my invention I have signed myname this 12th day of June 1928.
